Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.
Allow the engine to cool down if it was recently run.

2. Check Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick and pull it out again to check the oil level.
If overfilled, drain the excess oil through the oil drain plug.
If oil appears dirty or contaminated, consider a complete oil change.

3. Inspect Oil Filter

Locate the oil filter and check for proper installation.
If it is loose or leaking, tighten it or replace it with a new one.
Ensure the rubber O-ring from the old filter is not stuck on the engine block.

4. Replace Oil Pressure Sensor (if necessary)

Locate the oil pressure sensor, typically near the oil filter.
Disconnect the electrical connector and unscrew the sensor using a socket wrench.
Install the new sensor, ensuring it is torqued to the manufacturer's specifications (usually around 15-25 Nm).
Reconnect the electrical connector securely.

5. Reset Check Engine Light

Reconnect the battery.
Use the OBD-II scanner to clear any stored trouble codes.
Start the engine and monitor for the check engine light.
